터치스크린 입력 방식은 키보드나 마우스 등의 다른 주변 장치의 도움 없이 손이나 펜 등을 이용해 직접 화면에 접촉을 통한 입력을 수행한다. 이러한 입력 방식은 키보드, 마우스 등의 조작을 통해 포인팅 커서를 움직이거나 입력하는 방식에 비해 비교적 유연한 손가락을 이용한다는 점에서 입력의 유연성과 직관성을 극대화 시키는 장점을 가진다. 그러나, 손가락을 이용한 조작에 의해 야기되는 조작의 부정확성과 터치스크린을 활용한 새로운 인터페이스의 부재는 터치스크린 입력 방식의 큰 단점으로 지목되고 있다. 따라서, 본 논문에서는 터치스크린을 사용하는 이동 단말기의 효율적인 입력을 위한 다이얼 메뉴 유저 인터페이스를 제안한다. 본 기법은 사용자의 명령을 받기 위해 작은 아이콘 형태로 대기하고 있는 비활성화 상대, 사용자의 터치 명령을 받은 후 다이얼 형태로 인터페이스가 전개된 활성화 상태, 활성화 상태에서 원하는 명령을 찾고 실행하기 위한 네 가기 동작인 회전, 확대, 축소, 그리고 클릭으로 구성되어 있다. 본 기법을 통한 직관적인 조작은 터치스크린의 단점인 부정확한 포인팅을 극복하고, 터치스크린이 가지는 드래그 기능을 활용하여 메뉴 검색에 신속성을 부여한다.

The purpose of this study is to find out the factors that explain the sense of touch and preference of man-made leather. Date base of descriptors for man-made leather was collected by interviewing 50 consumers, 33 different kinds of commercial man-made leathers(synthetic leather and artificial leather) were assessed subjectively by 605 consumers using the 9-point scale of 34 pairs of bipolar descriptors based on the data base. Subjective ratings were analyzed by principal axis factoring with varimax rota-tion. The sense of touch of man-made leather is explained by five factors ; surface property stretchiness thickness& weight thermal property(warmth & coolness) and moisture property (sticky & clingy). The difference in the sense of touch of man-made leathers is mainly attributable to surface property and stretchiness. And the preference of man-made leathers is mainly attributable to surface property and stretchiness. And the preference of man-made leather is explained by three factors ; surface property stretchiness and quality. Higher preference is found in man-mad leather of better quality touch and softness.

In general, manufacturing error is originated from bad material, machine tool defection and tool breakage. When the manufacturing process is stable, the most of error come from the tool wear. In common on-machine measurement teaching probe and touch sensor are widely used however in this paper the electric touch point type automatic tool compensation system is developed the performance of it is validated and effective operating is proposed.

Touch screen using in portable devices is expanding continuously, has become particularly strong in mobile phones. These trends are able to open the "New Horizon" which refers the design and usability of mobile phones and provide "New Experience" which users have never been experienced on mobile phones. This research argues new usability issues and important points which can be occurred in touch based mobile phones as user experience point of view.

In recent years, the use of touch screens has expanded, and devices such as remote controllers have been developed in various ways to control and access contents at long range. The wireless-based touch screen is used in classroom, seminar room, and remote video conversation in addition to the TV remote control. The purpose of the study is to design a smart phone-based intuitive interface that can perform the role of a wireless mouse and a wireless keyboard at range using Bluetooth and to develop an application that integrates functions of a mouse and a keyboard. Firstly, touch interaction model for controlling software such as PowerPoint by connecting to a general PC on a smart phone has been studied. The most simple touch operation interface is used to reproduce the function of existing devices and design more simply. The studies of the extension of interfaces with various functions are important, but development of optimized interfaces for users will become more important in the future. In this sense, this study is valuable.

본 논문은 근접 무선 통신 기술(NFC)을 적용하여 박람회 지원 시스템을 구축한 사례와 관람객 행동 데이터(POB: Point of Behaviors)의 분석을 수행한 사례를 소개한다. NFC 기술이 박람회 공간에 적용됨에 따라 관람객은 휴대폰을 통해 다양한 정보를 획득하고 저장, 관리함으로써, 새로운 경험을 하게 되고, 전시자는 NFC 시스템을 통해 획득한 관람객에 대한 데이터 수집 및 분석이 가능하게 되어 관람객과의 CRM 기회를 갖게 된다. 본 연구에서는 '2013 내나라 여행 박람회'에 적용된 근접 무선 통신 기반 박람회 지원 시스템의 구축 내용을 소개하고, 수집된 NFC 태그 터치 데이터를 기반으로 날짜 및 부스 별 관람객 수, 관람객의 박람회 체류시간, 관람객 방문 부스 등의 분석을 수행하고, 박람회 현장에서 설문 조사를 실시하여 인구통계학적 정보, 박람회 만족도 등의 데이터를 수집하여 터치 데이터와 교차 분석을 수행한다. 또한 연관 규칙 분석 기법을 이용하여 관람객들이 방문한 부스들간의 연결 관계를 분석한다.

The delay between input action and visual interface feedback ("Latency") in a touchscreen inking task reduces the user's performance. When the latency is less than 2.38ms, the user cannot perceive the latency in dragging task. This value is difficult to achieve on recent touchscreens and general purpose computers. So, methods of predicting touch points to reduce perceptible latency has been proposed. In general, touch points prediction is not perfect. When using point prediction, feedback of the predicted points is displayed on the screen, after a while, erased when the actual points are displayed. When this task is implemented by software, it causes additional latency to work to erase predicted points feedback. It therefore propose a platform for rendering point prediction feedback without additional latency by the FPGA. This platform transmits input points and HDMI signals rendering feedback of input points to the FPGA. The FPGA draws the feedback of points predicted based on the input points on the HDMI and displays the screen. Since hardware rendering changes the HDMI signal every frame, it does not require erasing work and rendering can be done within an early time regardless of the amount of rendering, so we will reduce the latency.

The purpose of this study was to analyze the effect of the structural properties, the color characteristics and the texture of sight and touch on the tactile preferences for the black fabrics. Male and female university students were asked to evaluate the texture of sight and touch and tactile preference to the nine different black fabrics which were selected on the basis of the previous research results. Data were analyzed by using frequency analysis, mean, factor analysis, t-test, F-test, correlation and regression analysis. The texture of sight and touch for black fabrics was classified into four factors: smoothness, bulkiness, extensibility, firmness. This texture of sight and touch factors showed a significant correlative relationship to the structural properties and color characteristics of the black fabrics. There were significant differences according to black fabrics on the point of texture of sight and touch. The velvet was evaluated the most smooth fabric, while the velvet and fake leather were evaluated the most bulky fabrics. Also, the jersey and lace fabrics were evaluated the most extensible fabrics, while the melton was evaluated as the most firm fabrics. There were significant correlative relationships not only between the structural properties and the texture of sight and touch but also between the color characteristics and the texture for black fabrics. Also, among the structural properties, the color characteristics and the texture of sight and touch of black fabrics, major variable factor of influencing on the tactile preference was turned out to be the texture of sight and touch.

Reverse engineering is reproducing products by directly extracting geometric information from physical objects such as clay model wooden mock-up etc. The fundamental work in the reverse engineering is to acquire the geometric data for modeling the objects. This research proposes a novel method for data acquisition aiming at unmanned fast and precise measurement. This is come true by the sensor fusion with CCD camera using structured light beam and touch trigger sensor. The vision system provides global information of the objects data. In this case the number of data and position allocation for touch sensor is critical in terms of the productivity since the number of vision data is very huge. So we applied wavelet transform to reduce the number of data and to allocate the position of the touch probe. The simulated and experimental results show this method is good enough for data reduction.
